I have a question and hope to get your advice on it.
My tinnitus is very new, 2 weeks old and is kind of a dog whistle, very high frequency and a constant pulse like.
I couldn't figure out the cause of my Tinnitus yet and so do my ENT and reading other threads relating to initial tinnitus set-in, i am just trying to hang in there, not panic and trying to measure my response against it rather than the volume.
I am travelling home for Christmas and have a 24 hr long flight journey. Just wanted to know if this long flight and the jet engine sound could be fatal? Can this worsen my T?
What all precautions do you suggest?

@Harry, for long flights you might consider investing in a pair of Bose noise cancellation headphones Model 15, 25, 0r 3 (but not 20 or 20i). I would absolutely not allow your tinnitus - or concern that it might possibly get worse - interfere with your plans to travel home for Christmas.
